Finite Difference Time-Domain Modelling of Metamaterials: GPU Implementation of Cylindrical Cloak
Blog Article
Finite difference time-domain (FDTD) technique can be used to model metamaterials by treating them as dispersive material.Drude or Lorentz model can be incorporated into the standard FDTD algorithm for modelling negative permittivity and permeability.FDTD algorithm Burn Spray is readily parallelisable and Handstick Vacuum Cleaners can take advantage of GPU acceleration to achieve speed-ups of 5x-50x depending on hardware setup.Metamaterial scattering problems are implemented using dispersive FDTD technique on GPU resulting in performance gain of 10x-15x compared to conventional CPU implementation.
